Convert Quicktime to DVD

[Betty]

I'm looking for some preferably free software to covert a quicktime file to a dvd.

There seem to be lots of trial versions that a put a watermark in the file - which this can't have. (It would be helpful if they would note their trial version puts the watermark on - but they only seem to tell you that when you get ready to convert it. And after having done that repeatedly, I thought someone might have a direct recommendation for me.)

I only need to convert one file once so I'm reluctant to buy software to do this.

Can anyone make a suggestion for some software that will accomplish this? Even if it's a 30 day trial, as long as there isn't a watermark on it, that would work.
